Common Rectifier Configuration
The following parameters (common to all rectifiers) can be configured.
Parameter
Description
Where to find:
Phase-1
The serial number of the rectifier assigned as “Phase
1”. When this is set correctly, it enables the SC300 to
assign a phase number to all rectifiers.
Only applies to rectifiers that support phase detection,
including APR48-ES and NPR48-ES.
Shutdown All
Rectifiers Smart
Alarm
The SC300 can shut down all rectifiers under control of
this Smart Alarm number. Shutdown must be set to
Manual for this to work. Zero means no Smart Alarm
shutdown.
Shutdown All Solar
Chargers Smart
Alarm
The SC300 can shut down all solar chargers under
control of this Smart Alarm number. Shutdown must
be set to Manual for this to work. Zero means no
Smart Alarm shutdown.
Shutdown
Enable rectifier shutdown. This can be disabled,
Manual, or Automatic. Automatic means that LBRS is
active.

OVSD Set Point
Over Voltage Shut Down. A rectifier will shut down if
its output voltage exceeds this value.
Recommended value is 59.2V for 48V nominal systems,
28.6V for 24V nominal systems.
Start Up Delay
The delay from ac turn-on before the rectifier output
turns on.
Output Ramp-up
slope
The rate the rectifier output voltage increases after
start-up as a percentage of maximum current.
Current Limit
(DC) The output current limit of the rectifier. If set to
zero, then the output current limit is maximum.
AC Current Limit
The input current limit of the rectifier. If set to zero,
then the input current limit is maximum.
Rectifier Current
Share
Current Share ensures that the total output power of
the power system is evenly shared between all
rectifiers.
Set to
Enabled
unless there is a specific reason to
disable.
Power Share Offset The solar charger base voltage is increased by this
amount to ensure that the solar charger provides
maximum power when connected in parallel with AC
rectifiers.
